Does it work without the patches? Is it a regression, or still an improvement?

These errors are normal, 'usb part' seems to look for primary
partitions on a USB stick that is formatted as a floppy...

I have no explanation for this error, it could be related to the
filesystem on the USB stick itself.
I do not see any errors that USB itself is not working, the problems I
fixed were in the USB area, and they solved all the problems I
encountered with USB sticks on AT91SAM9261 (OHCI)
I would expect that it would work much better than before on your CPU...
Unfortunately I do not have a test environment for AT91CAP9, so I
cannot verify this issue here.
Kind Regards,
Remy
